Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a washing machine equipped with a water tank for recycling the i5 liquid and rinse water.

Conventional 114 structure and its problems In conventional fully automatic washing machines, the washing liquid and the final rinsing liquid are automatically drained. Therefore, when the washing liquid and the rinsing liquid are used twice, it is necessary to stop the timer of the washing machine at the end of the washing process and the rinsing process without draining the electrolytic liquid and the rinsing liquid. However, if you do it this way, the fully automatic washing machine will be completely clean! The function of automatically performing dehydration using a dehydrated ox is an X-added function. Therefore, devices have been developed that have a water storage tank and have the function of storing the aIC liquid and the rinsing liquid in the water storage tank. However, in this case, even if the washing liquid and rinsing liquid are dirty and cannot be reused, the water is automatically stored in the water tank, and the problem is that washing or rinsing is performed again with the dirty washing liquid or rinsing liquid. The disadvantage is that the inside of the water tank gets dirty and requires clean water to clean it.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, prevents dirt/ζ washing aρ solution and rinsing solution that cannot be reused from being stored in the water tank, and eliminates the need to perform washing and rinsing with dirty solution. An object of the present invention is to provide a washing machine equipped with a water tank that prevents clothes from being recontaminated and enables effective reuse of washing liquid and soot liquid.

Reference numeral 2 denotes a storage means for storing data regarding the washing liquid a and the rinsing liquid, and 3 a turbidity unit for determining the turbidity level based on the output of the turbidity detection means 1 and the turbidity data stored in the storage means 2. The output of the turbidity determining means 3 is inputted to the first stage 4 of the control. The control means 4 controls the pump driving means 6 and the valve driving means 6 to transfer the liquid to the liquid storage tank in the outer tank or to drain the liquid without transferring it to the water storage tank.

FIG. 2 is a circuit diagram showing the specific configuration of this embodiment. 7 is a washing and dehydrating tank for washing and dehydrating clothes, and has a large number of holes in the wall surface. Further, a pulsator 8 is provided inside the washing and dehydrating tank 7. Reference numeral 9 denotes an outer tank containing the washing/dehydration tank 7, which is suspended and supported by the main body 10, and the turbidity detection means 1 is provided at the bottom. 11il-j This is a motor for driving the washing/dehydration tank 7 and the pulsator 8. Reference numeral 12 denotes a water storage tank for transferring and storing the washing liquid and rinsing liquid in the outer tank 9. Reference numeral 13 denotes a pump driven by the pump driving means 6, which is operated to transfer the liquid in the outer tank 9 to the water storage tank 12 and store it, or to return the liquid in the water storage tank 12 to the outer tank 9. A water storage valve 14 is configured to remain open while the pump 13 is operating. A drain valve 15 is configured to be closed while the pump 16 is operating. Said water storage valve 14. Water control valve 15
is driven by the valve driving means 6.

16 is a microcomputer that uses a built-in program to determine the turbidity and pump 13. Water storage valve 14
．． It generates signals for driving the water control valves 16, respectively. Specifically, a storage section 16a that stores the turbidity setting values of the washing liquid and the rinsing liquid, an input 116bl that inputs the output from the turbidity detection means 1, and outputs a control signal to the pump driving means 5 and the valve driving means. output section -+
It controls the e c + Ail input group 16b, the storage section 16a, and the output section 160, respectively, and performs comparison operations, etc., and has a total of 5 arithmetic operations @181erl. Here, storage unit 1
6a is connected to the storage means 2 in FIG.
11 means 4 respectively.

Next, the operation of this embodiment will be explained. FIG. 3 shows the main part of a flowchart controlled by the microcomputer 16. After putting all the clothes and detergent into the washing and dehydrating tank 7, a switch is operated to start washing. With this operation, the microcomputer 16 opens the water supply valve in step 17 to supply water.

When water is supplied to the first water level, the process moves to step 18 and the washing starts. In step 19, within 1 to 3 minutes after starting washing,
At the time when the detergent has finished dissolving, the turbidity of the washing liquid is detected by the turbidity detection means 1, which comprises a light emitting element and a light receiving element, provided at the bottom of the outer tub 9. Next, when the washing is completed in step 2o, in step 21, the turbidity of the washing liquid at the end of washing is detected by the total turbidity detection means 1. Then, in step 22, the /A/llr liquid is classified by turbidity γ4j. The turbidity determining means 3 compares and determines whether this washing liquid is suitable for reuse with the data stored in the storage means 2, and determines whether or not to store the water. For example, the determination method is based on the turbidity A at the beginning of washing detected in step 19 and the turbidity B at the end of washing detected in step 21.
If it is less than a certain value α, it can be reused, and if it is more than the certain value α, it is determined that it cannot be reused. In this case, the storage means contains the value of α,
Also, the control method for storing and draining water is stored. If it is determined that the washing liquid can be reused, the micro pump 16 causes the valve driving means 6 to open the water storage valve 14 in step 23, and operates the pump driving means 6 in step 24 to start the pump 13. make it work. and,
In step 26, the washing liquid in the outer tank 9 is transferred to the water storage tank 12 and stored therein, and in step 26, the water storage valve 14'f! :close.

If it is determined in step 22 that the water cannot be reused, the microcomputer 16 causes the valve driving means 6 to open the water control valve 15 in step 27. Then, the washing liquid in the outer tub 9 is discharged to the outside of the machine. Note that the water storage valve 14 is closed at this time. After the water has been stored in the water tank, if the water has not yet been drained, proceed to the next step.3. The turbidity of the washing liquid is determined as described above.

Next, the turbidity determination of the rinsing liquid will be explained according to flowchart 1 in FIG. In step 29, the water supply valve is opened and water is supplied. When water is supplied to the set water level, close the water supply valve and proceed to step 3o.
Then, the turbidity C of the water supply liquid in the outer tank 9 is detected by the turbidity detection means 1 provided at the bottom of the outer tank 9. Next step 31
As a result, the pulsator 8 rotates completely in the reverse direction and starts rinsing. As the clothes are rinsed, dirt and detergent components contained in the clothes are released into the rinsing liquid, and the turbidity of the rinsing liquid gradually increases. When the rinsing process for a certain period of time is completed, the turbidity of the rinsing liquid is detected by the turbidity detection means 1 in step 32, and the turbidity of the rinsing liquid is determined in step 33. As in the case of washing liquid, the turbidity determination means 3 compares and determines whether the rinse liquid is suitable for reuse with the data stored in the storage means 2, and stores the water in the water storage tank 12. Determine whether or not. For example, if the rate of change between the turbidity C of the water supply liquid, the turbidity at the end of rinsing, and the turbidity of the rinsing liquid (D-C)/C is less than a certain value β, it can be reused. If it is β or more, it is determined that the oJ is to be reused. In this case, the value of β is stored in the storage means 2. If it is determined that the rinse solution can be reused,
The microcomputer 16 causes the valve and drive means 6 to open the water storage valve in step 34, and causes the pump drive means 5 to operate the pump 13 in step 35. Then, in step 36, the rinsing liquid in the outer tank 9 is transferred to the water storage tank 12 and stored therein. At this time, the drain valve 15 is closed. When the water storage in the water tank 12 is completed, the water storage valve 14 is closed in step 37, and the pump 13 is stopped. Then move on to the next step. Next, if it is determined that it cannot be reused in the turbidity determination in step 33, the microcomputer 16
In step 38, the drain valve 1 is activated by the valve driving means 6.
Let 5 open. Then, the rinsing liquid in the outer tank 9 is allowed to fall naturally to the outside of the machine and allowed to flow into IJ1 water. At this time, the water storage valve 14 is closed. Furthermore, if there is no drainage water 1 nearby, it is also possible to operate the pump 13 to discharge water. After the water is drained in step 39, the process proceeds to the next step.

As a method for determining turbidity, here we use the rate of change in turbidity (B-A
)/A, (D-1) 10, but it goes without saying that it is also easily possible to discriminate simply based on the absolute value of turbidity.

According to the above embodiment, when washing liquid or rinsing liquid is stored in a water tank for reuse, there is no need to make the mistake of storing dirty liquid that cannot be reused. This eliminates the problem of washing or rinsing again with washing liquid or rinsing liquid, and also reduces staining of the water tank.

Effects and non-inventions of the invention include i5 as a water storage tank for storing a layer liquid and a rinsing liquid;
A pump, a turbidity detecting means for detecting the turbidity of the liquid in the washing and dehydrating tank, a turbidity determining means for determining the turbidity level, and a pump driving means and a valve driving means according to the determined turbidity. Because it is equipped with a control means, when storing ecWA liquid or rinsing liquid for reuse, it does not automatically store dirty liquid that would stain clothes if reused. Drain. Therefore, if you accidentally store dirty liquid in the water tank and empty it, you may contaminate the tank.
A good fully automatic washing machine that can prevent clothes from being re-contaminated using the dirty liquid and effectively utilize the washing liquid and rinse Ik? :It is something that can be provided.
